Colo~o <br />11mve1sRv <br />• <br />April 30, 1996 <br />Daryl E. Mergen <br />Western Ecological Resource, Inc. <br />711 Walnut Street <br />Boulder, CO 80302 <br />Dear Mr. Mergen: <br />Colorado Natural Heritage Program <br />College of Natural Reaourca <br />103 Natural Resources <br />Fort Collins. Colorado 80523.1401 <br />(970)491-1309 <br />FA7C: (970) 491-0279 <br />The Colorado Natural Heritage Program (CNHP) is in receipt of your recent request for <br />information regazding federal or state threatened, endangered, rare or sensitive plant species neaz <br />Cameo in western Colorado. In response, CNHP has seazched its Biological and Conservation <br />Datasystem for such plant species documented from the areas on the revised map you provided <br />to us on April 24, 1996. According to the data currently in our files, there aze no occurrences <br />of such plants recorded within the project areas. Some information about other plant and natural <br />community occurrences in the immediate vicinity is provided. <br />One occurrence of Popular deltoides ssp wislizenii/t2hus trilobata (a Fremont's cottonwood <br />riparian forest community) from 1984 was documented in T10S R98W section 26. This <br />community is ranked imperiled across its range (G2) and in Colorado (S2). <br />One occurrence of Gilia stenothyrsa (Narrow-stem gilia) from 1993 was documented in nearby <br />Main Canyon in T10S R98W section 22. Another occurrence of this plant from 1981 was <br />mapped in Moulton Valley in T1N R1E section 26. The latter location is considered accurate <br />within approximately one square mile. Gilia stenothyrsa is found in open, often alkaline places <br />at lower elevations, in sandy or sometimes clay soil (Cronquist et al. 1984). This plant is <br />ranked vulnerable across its range (G3) and critically imperiled in Colorado (SI). It is listed <br />as a Sensitive Species by the Bureau of land Management. <br />One occurrence of I.omatium eastwoodiae (Eastwood desert-parsley) from 1978 was documented <br />further up Coal Canyon in T11S R98W section 5. It is found in dry or loamy sand (Hartman <br />1994). This plant is ranked common to vulnerable across its range (G3G4) and in Colorado <br />(S3S4) and has been watchlisted by CNHP. However, it is listed as a Sensitive Species by the <br />Bureau of Land Management. <br />• Also enclosed aze two additional documents you may find useful. The first is a list of rate, <br />threatened and endangered species and significant natural communities known from Mesa <br />County. This azea includes several ecoregions and a wide variety of ecosystems. Therefore, not <br />Nature <br />Conservanry® <br />
